The invention relates to a four-port track circuit system, which comprises a digital control unit capable of sending and receiving two paths of information, the digital control unit comprises an information acquisition module used for acquiring two paths of information, a double-CPU module and a signal generation and re-inspection module used for processing the information, which are connected in sequence, and the double-CPU module is connected with a relay module used for representing a section state. According to the invention, two paths of independent multi-coded frequency shift signals and two paths of independent frequency shift signal receiving ports can be output, and frequency shift information returned by a steel rail can be demodulated, so that whether a section is occupied by a train or not can be judged. By adopting the system, only different configurations and transmission devices need to be modified, the problems of all sections in China at present can be solved, and the availability and cost performance of the system are improved due to the fact that the number of the devices is reduced and the system structure is simplified.

    本发明涉及一种四端口轨道电路系统,所述四端口轨道电路系统包括可发送和接收两路信息的数字控制单元,所述数字控制单元包括依次连接的用于获取两路信息的信息获取模块、双CPU模块和用于对所述信息进行处理的信号生成及回检模块,所述双CPU模块连接有用于表示区段状态的继电器模块。本发明可输出两路独立的多种编码的移频信号及两路独立的移频信号接收端口,可对钢轨返回的移频信息进行解调,从而判断出区段是否有列车占用。采用该系统仅需修改不同的配置及传输设备,可满足目前国内所有区段的问题,由于设备数量减少,且系统结构简化,提高了系统的可用性及性价比。
